Description

Technical Field

[0001] This invention relates to the field of sound barrier top rod installation, and in particular to a sound barrier top rod installation trolley for rail transit. Background Technology

[0002] With urban development, rail transit is frequently seen or used in daily life. Sometimes rail vehicles pass through densely populated residential areas. In order to reduce the impact of noise on residential areas, sound barriers are usually set up on both sides of the track.

[0003] Currently, in the construction of traditional sound barriers, multiple columns are usually installed on both sides of the track. Then, a crane is used to lift the top rods. Workers stand on the top of the platform and swing the top rods so that the ends of the horizontally placed top rods are aligned with the tops of the columns and connected to complete the construction of the sound barrier.

[0004] In response to the current situation, the inventors found that hoisting the top rods one by one using the traditional method is cumbersome and inefficient, and further improvements are needed. Summary of the Invention

[0005] The purpose of this application is to provide a trolley for installing the top rod of a rail transit sound barrier, which can facilitate the installation of the top rod, reduce the workload of workers, and improve work efficiency.

[0006] This application provides a rail transit sound barrier top rod installation trolley, which adopts the following technical solution:

[0007] A rail transit sound barrier top rod installation trolley includes: a trolley frame; lifting devices disposed on both sides of the trolley frame for lifting the top rod; a plurality of support plates disposed at intervals on the conveying section of the lifting devices for carrying the top rod; a movable frame slidably disposed on the top of the trolley frame and symmetrically disposed thereon; a drive assembly disposed on the top of the trolley frame for driving the movable frame to move horizontally; and a support mechanism disposed on the movable frame for supporting the top rod on the support plates to a predetermined height.

[0008] By adopting the above technical solution, during the assembly of the top rod and the column, the lifting device can continuously raise the top rod to a predetermined height using the support plate, making it easy for the workers on the trolley to install the top rod. The movable frame, driven by the drive component, can drive the support mechanism to support the top rod, so that the two ends of the top rod are aligned with the top of the column, facilitating the assembly of the top rod and the column. This solution can effectively reduce the workload of the workers and improve work efficiency.

[0009] This application further provides that the lifting device includes: a drive sprocket installed at the bottom of the trolley frame; a driven sprocket installed at the top of the trolley frame; a conveyor belt connecting the drive sprocket and the driven sprocket; and a first driving member installed at the bottom of the trolley frame for driving the drive sprocket to rotate, wherein the support plate is installed on the conveyor belt.

[0010] By adopting the above technical solution, when it is necessary to lift the top rod, the first drive component can be activated to drive the drive sprocket to rotate. The drive sprocket and the driven sprocket cooperate with each other, and the top rod can be easily lifted to the predetermined height by the conveyor belt. The operation is simple and saves time and effort.

[0011] This application further provides that: symmetrical strips are fixed at both ends of the support plate on the side away from the conveyor belt, the strips are provided with strip grooves along their length, a limiting plate for blocking the top rod is slidably installed between the strips, and a moving block adapted to the strip groove is fixed on each side of the limiting plate. A compression spring for connecting the two is provided between the inner wall of the end of the strip groove and the moving block, and a limiting member for limiting the displacement distance of the moving block is also provided on the strip.

[0012] By adopting the above technical solution, the limiting plate can restrict the top rod during the lifting process, reducing the possibility of the top rod rolling off the support plate during the lifting process, thereby improving the safety performance of the top rod lifting process.

[0013] This application further provides that the supporting mechanism includes: a plurality of telescopic cylinders vertically installed on the top of the mobile frame; a support plate installed on the top of the telescopic cylinders; and an adjustment component disposed on the mobile frame for adjusting the height of the support plate.

[0014] By adopting the above technical solution, the support plate can support the top rod. When it is necessary to adjust the height of the top rod so that it is aligned with the top of the column, it can be easily operated by adjusting the components. The whole process is more convenient than the traditional hoisting method.

[0015] This application further specifies that the adjustment assembly includes a threaded rod rotatably mounted on a movable frame in a vertical direction, the threaded rod threaded through a support plate, and a rotating frame fixed on the threaded rod.

[0016] By adopting the above technical solution, when it is necessary to adjust the height of the support plate, the rotating frame can be held to drive the threaded rod to rotate. During the rotation of the threaded rod, the telescopic cylinder can be raised and lowered, thereby driving the support plate to adjust its height.

[0017] This application further provides that: the movable frame is slidably mounted with a lifting frame for supporting the support mechanism in the vertical direction, and the movable frame is provided with a third driving component for driving the lifting frame.

[0018] By adopting the above technical solution, the lifting component, driven by the third drive component, can significantly adjust the height of the entire support plate, making it convenient for the support mechanism to transfer the top rod from the support plate. This design is simple to operate and has obvious effects.

[0019] This application further provides that: mounting columns are fixed at both ends of the support plate along its length, a fixing plate is installed between the mounting columns, a conveying plate for conveying the top rod along its length is slidably mounted on the fixing plate, and a second driving member for driving the conveying plate to slide is also provided on the support plate.

[0020] By adopting the above technical solution, when the top rod is placed on the conveyor plate, the conveyor plate can be driven to slide by activating the second drive component. The conveyor plate can easily adjust the displacement of the top rod in the length direction, so that the end of the top rod is as close as possible to the top of the column, which facilitates the subsequent installation of the top rod and the column.

[0021] This application further provides that: both sides of the fixed plate in the width direction are equipped with rotating shafts whose length direction is consistent with the length direction of the fixed plate; symmetrical and arc-shaped cross rods are rotatably sleeved on the rotating shafts; a clamping rod for clamping the top rod is installed at the end of the cross rod away from the rotating shaft; and a fourth driving member for driving the clamping rods to move closer or further apart is provided on the support plate.

[0022] By adopting the above technical solution, when the supporting mechanism supports the top rod, the fourth driving component can drive the clamping rods to move closer to each other, so that the clamping rods can clamp and limit the top rod from both sides, thereby reducing the possibility of the top rod rolling down during installation.

[0023] This application further specifies that the fourth driving component includes: sliding blocks symmetrically mounted on both sides of the width of the support plate; a telescopic rod with one end hinged to the sliding block and the other end fixed to the end of the cross rod away from the clamping rod; a bidirectional threaded rod with a horizontal thread passing through the two sliding blocks; and a servo motor mounted on the support plate for driving the bidirectional threaded rod to rotate.

[0024] By adopting the above technical solution, when the servo motor is turned on, the bidirectional threaded rod can be driven to rotate, thereby driving the symmetrical sliding blocks to move closer or further apart. During the sliding process of the sliding blocks, the clamping rod can be easily moved closer or further apart to achieve the restriction or release of the top rod.

[0025] This application further provides that: a fixing rod is inserted between the end of the clamping rod and the end of the cross rod, and a fixing ring is threadedly connected to the end of the fixing rod.

[0026] By adopting the above technical solution, the fixed ring and the fixed rod cooperate with each other, which can facilitate the assembly and disassembly of the clamping rod. At the same time, when it is necessary to adjust the clamping angle of the clamping rod, it can also be achieved by rotating the fixed ring. Although the design is simple, the effect is obvious.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] By setting up a lifting device and spaced support plates, the top rod can be continuously lifted to the predetermined height, which is obviously more efficient than the traditional single-rod hoisting method. The support mechanism can transfer the rod from the support plate, making it easier to assemble the top rod with the column.

[0029] By setting up an adjustable-height support plate and a sliding conveyor plate, when the top rod is transferred to the support mechanism, not only can the height of the top rod be adjusted in the vertical direction, but the top rod can also be moved along its length, so that the top rod can be quickly aligned with the top of the column to achieve precise assembly of the two.

[0034] The present application will be further described in detail below with reference to the accompanying drawings.

[0035] This application discloses an embodiment of a rail transit sound barrier top rod installation trolley, such as... Figure 1 and Figure 2As shown, it includes: a trolley frame 1. In this embodiment, the trolley frame 1 can be driven by a power source so that the trolley frame 1 can move. Lifting devices are installed on both sides of the trolley frame 1. Multiple support plates 2 are installed at intervals on the conveying part of the lifting device. When it is necessary to lift the top rod, the lifting device can be turned on, and the top rod can be placed one by one on the spaced support plates 2, so as to realize the continuous conveying of the top rod.

[0036] In this embodiment, the lifting device includes: a drive sprocket 11 installed at the bottom of the trolley frame 1, a driven sprocket 12 installed at the top of the trolley frame 1, and a conveyor belt 13 connected between the drive sprocket 11 and the driven sprocket 12. At the same time, a first driving member for driving the drive sprocket 11 to rotate is also installed at the bottom of the trolley frame 1. It should be noted that the support plates 2 are spaced apart on the conveyor belt 13. When the first driving member is activated, the drive sprocket 11 can be driven to rotate. With the drive sprocket 11 and the driven sprocket 12 rotating together, the lifting of the top rod can be easily achieved.

[0037] In order to facilitate the transfer of the top rod on the support plate 2 to the predetermined position, in this embodiment, a symmetrical movable frame 3 is slidably installed on the top of the trolley frame 1. The sliding direction of the movable frame 3 is perpendicular to the conveying direction of the lifting device. At the same time, a drive assembly is also installed on the top of the trolley frame 1. The drive assembly is used to drive the movable frame 3 to move along the predetermined direction. In addition, a support mechanism is also provided on the movable frame 3.

[0038] When the lifting device raises the top rod to the predetermined height, the drive assembly can be activated to drive the moving frame 3 to move. The support mechanism on the moving frame 3 can support the top rod on the support plate 2. At this time, the drive assembly drives the moving frame 3 to move in the opposite direction. Under the action of the support mechanism, the end of the top rod can be aligned with the top of the column to facilitate the construction work of the workers.

[0039] Considering that the top rod is prone to slippage during the lifting process of the support plate 2, in this embodiment, symmetrical strips 21 are fixed at both ends on the side of the support plate 2 away from the conveyor belt 13. A strip groove is formed along the length direction on the side of the strips 21 that are close to each other. A limiting plate 22 is slidably installed between the strips 21. A movable block 23 adapted to the strip groove is fixed on the side of the limiting plate 22. At the same time, a compression spring 24 is installed between the inner wall of the end of the strip groove away from the support plate 2 and the movable block 23. The end of the compression spring 24 is connected to the movable block 23 and the end of the strip groove, respectively. Under the action of the compression spring 24, the limiting plate 22 will extend beyond the edge of the strip 21 to restrict the top rod.

[0040] Considering that the size of the top rod may vary in practice, it is necessary to adjust the length of the limit plate 22 extending from the support plate 2. In this embodiment, a limit member is provided on the strip 21. The limit member is used to limit the displacement distance of the moving block 23. The limit member is an abutment screw threaded on the outside of the strip 21. After the moving block 23 is adjusted to the correct position, the abutment screw can be rotated so that the tip of the abutment screw abuts against the moving block 23 to limit the moving block 23.

[0041] like Figure 1 and Figure 3 As shown, the support mechanism includes: multiple telescopic cylinders 31 vertically installed on the top of the mobile frame 3, the telescopic cylinders 31 being vertically arranged, a support plate 32 being fixed at the top of the telescopic cylinders 31, and an adjustment component being provided on the mobile frame 3 for adjusting the height of the support plate 32.

[0042] In this embodiment, the adjustment component includes a threaded rod 30 that is rotatably mounted on the movable frame 3 in the vertical direction, and the threaded rod 30 passes through the edge of the support plate 32. For ease of operation, a rotating frame is also fixed on the threaded rod 30. In addition, it should be noted that a lifting frame 36 for supporting the support mechanism is slidably mounted on the movable frame 3 in the vertical direction, and a third driving component for driving the lifting frame 36 is also mounted on the movable frame 3.

[0043] When it is necessary to move the top rod, the third drive component can be activated to drive the support plate 32 to rise. The support plate 32 can lift the top rod on the support plate 2. As the moving frame 3 moves, the top rod can be easily transferred out of the support plate 2. When there is a height difference between the two ends of the top rod and the top of the column, in addition to activating the third drive component, the rotating frame can also be rotated to drive the threaded rod 30 to rotate. When the threaded rod 30 rotates, it can also drive the support plate 32 to make fine adjustments to the height. The cooperation between the third drive component and the threaded rod 30 can more accurately adjust the top rod to the predetermined installation height.

[0044] Considering that in practice, it is sometimes necessary to move the top rod along its length, in this embodiment, mounting columns 33 are fixed at both ends of the support plate 32 along its length, and a fixing plate 34 is installed between the mounting columns 33. A conveying plate 35 is slidably installed on the fixing plate 34, and the bottom of the conveying plate 35 is slidably installed on the fixing plate 34 through two sliding blocks 350. The conveying direction of the conveying plate 35 is consistent with the length direction of the top rod. A second driving member for driving the conveying plate 35 to slide is also provided on the support plate 32.

[0045] When the second drive unit is activated, it can drive the conveyor plate 35 to slide. When the conveyor plate 35 slides, it can drive the supporting push rod to move together until the top of the push rod is aligned with the top of the column.

[0046] In addition, considering that the push rod may slide or roll on the conveying plate 35 in practice, in order to improve the overall stability of the push rod, in this embodiment, a rotating shaft 4 is installed on both sides of the fixed plate 34 in the width direction. The length direction of the rotating shaft 4 is consistent with the length direction of the fixed plate 34. A symmetrical cross rod 41 is rotatably sleeved on the rotating shaft 4, and the cross rod 41 is arc-shaped. A clamping rod 42 is also installed at the end of the cross rod 41 away from the rotating shaft 4. At the same time, a fourth driving member is also provided on the support plate 32. The fourth driving member can drive the clamping rod 42 to move closer or further away from each other.

[0047] It should be noted that in order to hold the push rod, the width of the conveyor plate 35 is smaller than the diameter of the push rod. When the push rod is placed on the conveyor plate 35, the fourth drive unit can be activated to drive the clamping rods 42 to move closer to each other, so that the clamping rods 42 can restrict the push rod from both sides to reduce the possibility of the push rod slipping off the conveyor plate 35.

[0048] In this embodiment, the fourth driving component includes: sliding blocks 43 slidably mounted on both sides of the width of the support plate 32 and symmetrically opposite each other; a telescopic rod 44 is hinged to the sliding blocks 43; one end of the telescopic rod 44 away from the sliding blocks 43 is fixed to the end of the cross rod 41 away from the clamping rod 42; at the same time, a bidirectional threaded rod 45 is horizontally threaded between the two sliding blocks 43; and a servo motor 46 is mounted on the support plate 32, which is used to drive the bidirectional threaded rod 45 to rotate.

[0049] When the servo motor 46 is turned on, it can drive the bidirectional threaded rod 45 to rotate. When the bidirectional threaded rod 45 rotates, it can easily drive the sliding blocks 43 to move closer or further apart, thereby achieving clamping or releasing the top rod.

[0050] In addition, a fixing rod 47 is inserted between the end of the clamping rod 42 and the end of the cross rod 41. A fixing ring 48 is threaded to the end of the fixing rod 47. The advantage of this arrangement is that the fixing ring 48 and the fixing rod 47 cooperate with each other, which can facilitate the assembly and disassembly of the clamping rod 42. At the same time, when it is necessary to adjust the clamping angle of the clamping rod 42, it can be easily adjusted by rotating the fixing ring 48.

[0051] It should be noted that in this embodiment, the drive component and the third drive component can both be common pneumatic cylinders or hydraulic cylinders, the first drive component can be a common servo motor, and the second drive component mainly includes a servo motor and gears. At the same time, a rack that meshes with the gears is provided at the bottom of the conveyor plate 35. When the servo motor is turned on, the conveyor plate 35 can be driven to convey. Since these power sources are all common, they will not be described in detail here.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
